8/6:Arizona Cardinals wide receiver Greg Little has impressed so far this preseason, moving up the depth chart in the process. From a camp body to taking some first team reps, Little has shown some of his early NFL career form in training camp and should be an interesting name to watch throughout the preseason. If Little can become one of the team's starting receivers, he could potentially return flex value at an incredible value. Keep an eye on how Little does this preseason before committing a last round pick to him.--Martin K - RotoBallerSource: Jess Root
